equivalent of "testparm" in an imputed Cox model

[Emmanuel Wiernik]

Hello,

I'm using a Cox model with imputed covariates (and taking competitive risks into account, even if I'm not sure that this change my concern):

"mi estimate, hr: stcrreg outcome variable1 variable2"

I'd like to calculate the overall interaction p between variable1 and variable2 (variable 1 has 2 categories and variable2 has 3 categories). I usually use "testparm variable1##variable2" but in this model it doesn't work.

Thank you very much in advance for your help.

See this thread for a discussion of possible solutions. Essentially you will use multiple test statements.
